A brake cylinder configured to provide braking signaling to an automotive simulator, the brake cylinder includes a damper housing, a resilient damper arranged within the damper housing and a piston configured to move a block in the axial direction at least partially into the damper housing towards said resilient damper. The block comprises a mechanical stop configured to limit the axial movement of the piston in the axial direction. The brake cylinder further has a sensor configured to measure a response to movement of said piston and send a signal to a processor indicative of that movement. The brake cylinder is configured to be connected to a brake pedal. The mechanical stop divides the braking process into two phases a first phase where the pedal can be depressed and a second phase where the pedal cannot be pressed further due to the mechanical stop. In one variant the brake cylinder is a purely mechanical system with only the damper housing or in combination with a single cylinder chamber. Alternatively, the described cylinder chamber is a slave chamber for use in a hydraulic brake cylinder also including a master chamber in fluid connection with the slave chamber via a channel.

A brake cylinder for use with an automotive simulator includes a brake cylinder housing having a master chamber, a slave chamber, a wall disposed therebetween and at least one channel configured to provide fluid communication between the master chamber and the slave chamber. In some variants, the at least one channel may be an opening configured to provide fluid communication between the master chamber and the slave chamber, in another variant the channel may be an external channel such as a tube. The brake cylinder also includes a master piston configured to pressurize fluid in the master chamber when a brake pedal is pressed. The brake cylinder further includes a slave piston and a pressure sensor disposed in fluid communication with the brake cylinder. The pressure sensor is configured to measure pressure in the chambers and send a signal to a processor indicative of movement of the brake pedal. When pressurizing fluid in the master chamber, the master piston is configured to drive fluid from the master chamber to the slave chamber via the at least one channel to increase pressure in the slave chamber.

A mounting assembly for fixing a component of a vehicle brake system to a vehicle structure. The mounting assembly includes a mounting portion of the vehicle structure having a through hole, a mounting element of the vehicle brake system having a through hole, and a bolt extending through both through holes. Furthermore, a nut engages the bolt such that the mounting portion is attached to the mounting element via the bolt and the nut. Additionally, an elastic bushing is provided having a first bushing collar which extends from a bushing body in a radial direction. The first bushing collar further extends on a first axial side of the corresponding mounting portion or mounting element. Furthermore, a vehicle is presented which includes such a mounting assembly and a vehicle brake system. A component of the vehicle brake system is fixed to a structure of the vehicle via the mounting assembly.

A combination hydraulic master cylinder comprising two typically parallel pumps disposed within adjacent compartments within a common body of the combination hydraulic master cylinder. Each pump's piston physically pressurizes hydraulic fluid that has been separately drawn into its respective cylinder and in hydraulic isolation, however the proximate location of the independent pumps allows for convenient operation using one hand on one handlebar with reduced congestion of space rather than the more conventional arrangement of two separate master cylinders. The pistons are actuated mechanically using dedicated levers mounted externally to the cylinders. The levers are adjustable in the manner to which they are disposed to the pistons. One lever is oriented such that it is operable using a finger pull action; the second lever is oriented such that it is operable using a thumb push action.

A bicycle hydraulic operating device is basically provided with a base member, a piston, an operating member and a hydraulic reservoir. The base member includes a cylinder bore. The piston is movably disposed in the cylinder bore. The operating member is coupled to the piston to move the piston within the cylinder bore. The hydraulic reservoir includes a hydraulic reservoir tank and a reservoir lid. The hydraulic reservoir is provided on the base member and is fluidly connected to the cylinder bore by a fluid passage. At least part of one of the base member and the hydraulic reservoir includes a fluid inspection portion making visually perceptible therethrough at least a portion of a hydraulic fluid flow path that includes the hydraulic reservoir, the cylinder bore and the fluid passage.

A bicycle control device includes a housing member, a control lever member, a shift-operating mechanism and a hydraulic fluid pressure generator. The housing member has an attachment part for attachment to a handlebar, and a grip part extending longitudinally between first and second ends of the grip part. The attachment part is provided on the first end of the grip part. The attachment part is provided on the first end of the grip part. The control lever member is pivotally provided with respect to the housing member. The shift-operating mechanism is supported by the housing member. The shift-operating mechanism includes a control cable attachment part that is configured to be coupled to a shifting device by a control cable. The hydraulic fluid pressure generator has a cylinder provided in the grip part of the housing member, and a piston movably disposed within the cylinder by movement of the control lever member to generate fluid pressure for controlling a braking device. The cylinder is disposed closer to the second end of the grip part than the shift-operating mechanism.
